Night Shift Handbook for the Abyssal Hospital

The story takes place in Longcheng in the near future.

An invisible disaster known as “cognitive contamination” quietly descends, twisting the physical laws in specific areas and creating abnormal zones called “Rule-bound Secret Realms.”

The official organization known as the “Night Watch” suppresses information and secretly recruits “Qualifiers,” people with a natural resistance to the contamination, to deal with the threat.

The protagonist gets caught up in it by chance and discovers that he is inside Longcheng’s most dangerous Rule-bound Secret Realm: Abyssal Hospital.
